Quantification of Physical Activity and Sedentary Time in Adults with Cerebral Palsy.

  • Published on Nov. 21, 2014

Purpose: Objective and subjective quantification of habitual physical activity (HPA) and sedentary time in ambulatory and nonambulatory adults with cerebral palsy (CP). Methods: We recruited a clinical sample of adults with CP (N=42; 21 female; mean age: 33.5 yr, SD 12.3 yr; Gross Motor Function Classification System (GMFCS) distribution: Level I (n=5), Level ...


Variability in Measuring Physical Activity in Children with Cerebral Palsy.

  • Published on May 12, 2014

Introduction: To establish the variability in the measurement of habitual physical activity (HPA) using the ActiGraph(R) GT3X+ accelerometer in children with cerebral palsy (CP). Method: Repeated measures: Independently ambulant children with unilateral CP (n=30; aged 11y3m [2y4m]) completed standardized tasks over two consecutive days wearing an ...


Does a waist-worn ActiGraph accelerometer quantify community ambulation in persons with multiple sclerosis?

  • Published on Nov. 9, 2012

Abstract: Accelerometry has been recognized as a method of objectively measuring community ambulation in persons with multiple sclerosis (MS). However, the assumption that walking itself serves as a major contributor to the accelerometer signal has yet to be tested. This study examined the assumption that community-based walking is a primary ...


T2 Relaxation Time and Activity in Boys with Duchenne Muscular Dystrophy

  • Published on Summer 2013

Abstract Duchenne muscular dystrophy (DMD) is an inherited neuromuscular disorder characterized by progressive muscular degeneration. It is unknown what amount of activity is beneficial or detrimental to dystrophic muscle. This study examined functional mobility, activity, and T2 relaxation time in boys with DMD. DMD subjects were divided into two groups (...


Assessment of Measures of Physical Activity of Children with Cerebral Palsy at Home and School: A Pilot Study

  • Published on Oct. 27, 2013

Background Home and school are important settings where children can accrue health promoting physical activity (PA). Little is known about the PA levels and associated environmental characteristics at home and school in children with cerebral palsy (CP). An observational tool - Behaviors of Eating and Activity for Children’s Health ...


Comparison of Pedometer and Accelerometer Derived Steps in Elderly Individuals With Parkinson's Disease or Osteoporosis Under Free-Living Conditions.

  • Published on Dec. 4, 2013

Aim To compare self-reported pedometer steps with accelerometer steps under free-living conditions in individuals with Parkinson's disease (PD) or osteoporosis (OP). Methods Seventy-three individuals with PD and 71 individuals with OP wore a pedometer (Yamax LS2000) and an accelerometer (Actigraph GT1M/GT3X+) simultaneously for one week. Results Fifty-one individuals ...


Comparison of ActiGraph activity monitors in persons with multiple sclerosis and controls

  • Published on May 2013

Purpose The current study compared output from the vertical axis of two models of ActiGraph accelerometers under free-living and laboratory conditions in persons with multiple sclerosis (MS) and matched controls. Methods The sample included 41 cases of MS and 41 controls matched by age, sex, height and weight. Participants concurrently wore 7164 and ...


A novel conceptual framework for balance training in Parkinson’s disease-study protocol for a randomised controlled trial

  • Published on Sept. 27, 2012

Study Protocol Background There is increasing scientific knowledge about the interaction between physiological (musculoskeletal, neuromuscular, cognitive and sensory) systems and their influence on balance and walking impairments in Parkinson’s disease. We have developed a new conceptual framework for balance training, emphasising specific components of balance control related to Parkinson’...


Physical Activity Measurement Using MTI (Actigraph) Among Children With Cerebral Palsy

  • Published on 08/2010

Objective To investigate the validity of MTI accelerometer as a physical activity (PA) measurement instrument for children with cerebral palsy (CP). Design Participants were classified within Gross Motor Function Classification System I to III and took part in 2 activity sessions: (1) a structured activity protocol with increasing intensities and (2) a free ...
